PSG has now claimed the season-opening trophy on 14 separate times.
The Parisian giants needed a stoppage-time equaliser followed by a successful spot-kick decider to get past Marseille in the Gulf and secure a record-extending fourth consecutive Trophee des Champions victory.
The Champions League holders seemed to be coasting towards a straightforward triumph in the showdown featuring the Ligue 1 champions and the French Cup holders after Ousmane Dembele found the scoring in the opening stages.
However, the southern French side struck twice late to seize a shock advantage. Initially, the English forward scored from the penalty spot, before Willian Pacho unfortunately turned the ball into his own net for an own goal.
In a remarkable twist of events, Goncalo Ramos grabbed a crucial equaliser in the final seconds to force the match into a deciding shootout. The Parisian shot-stopper Chevalier then emerged as the key figure, stopping decisive kicks from Matt O'Riley and Traore.
In the shootout, Ramos, Vitinha, the full-back, and the young talent all converted with composure for PSG to complete a convincing shootout win.
The record champions PSG, who met last season's Ligue 1 second-placed team Marseille after achieving a league and cup double, have now lifted this competition for the twelfth time in the past thirteen seasons.
